    Hi m_vedsharma,

    I would recommend using the data you receive over UART to set the value of the string characteristic of the data service in Project Zero. When you receive data, you can write the data by using DataService_SetParameter(DS_STRING_ID, sizeof(uartData), void *uartData). By default, the string characteristic holds 40 bytes. If you have more than 40 bytes you wish to set, you will need to increase the size of DS_STRING_LEN in data_service.h.
